Pulse Wire - Where ???

[SteveGRF]

Hi all, could somebody offer a little tech advice, just installed a second hand Alpine
Sat Nav unit into the wifes beetle, not sure where to wire the pulse wire into. I have
an idea it should be the Speedo or Tach but ???. Also would it be a +V or -V ... any
help please.

Steve I think you will find this vehicle is CAN bus and as such you will need a CAN bus interface to convert the CAN high/low signals to give you the speed pulse signal you require.

I may have one I could sell you cheaper (need to have a look) so let me know how you get on!
